Description:

The MTD6502B device is a 3-phase full-wave driver for brushless sensorless DC motors. It features 180° sinusoidal drive, high torque output and silent drive. With adaptive features, parameters and a wide range of power-supplies (2V to 5.5V), the MTD6502B device is intended to cover a wide range of motor characteristics, while requiring minimum external components. Speed control can be achieved through either power supply modulation or pulse-width modulation (using the PWM digital input pin).

Features:

• Position Sensorless BLDC Drivers (No Hall Sensor Required)

• 180° Sinusoidal Drive, for High Efficiency and Low Acoustic Noise

• Support 2V to 5.5V Power Supplies

• Direction Control:

- Forward direction: connect DIR pin to GND or leave floating

- Reverse direction: connect DIR pin to VDD

• Speed Control through Power Supply Modulation (PSM) and/or Pulse-Width Modulation (PWM)

• Built-in Frequency Generator (FG Output Signal)

• Built-in Lock-up Protection and Automatic Recovery Circuit (External Capacitor not Necessary)

• Built-in Over Current Limitation

• Built-in Thermal Shutdown Protection

• No External Tuning Required

• Available Packages:

- 3 mm x 3 mm TDFN-10

Applications:

• Notebook CPU Cooling Fans

• 5V 3-Phase Brushless DC Motors
